Structural loads, beam deflection, soil mechanics, and bridges — modelled
Civil engineering simulations apply structural and geotechnical mechanics to infrastructure design. Finite-element beam and truss models compute internal forces, bending moments, and deflection under user-applied point and distributed loads, visualising stress concentration and failure margins. Suspension-bridge cable simulations solve the catenary equation and show how live traffic loads redistribute tension across cables and hangers.
Soil consolidation simulations model Terzaghi's one-dimensional consolidation theory, showing pore-pressure dissipation and settlement over time for clay layers under embankment loads. Foundation bearing-capacity models compute collapse loads for shallow footings using Prandtl and Meyerhof failure mechanisms. These are the computational tools taught in structural analysis and geotechnical engineering courses and used daily in bridge design and building foundation assessment.
Each simulation in this category is built with accuracy and interactivity in mind. The underlying mathematical models are the same ones used in academic research and professional engineering — just made accessible through a web browser. Changing parameters in real time and observing the results is one of the most effective ways to build intuition for complex scientific and engineering concepts.
